softxiang opened a new issue #2215: 与spring结合使用时循环依赖导致事务失效问题 URL: https://github.com/apache/incubator-dubbo/issues/2215 - [√] I have searched the [issues](https://github.com/apache/incubator-dubbo/issues) of this repository and believe that this is not a duplicate. - [√] I have checked the [FAQ](https://github.com/apache/incubator-dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 2.5.7 * Operating System version: win10 * Java version: 1.8 ### Step to reproduce this issue 有A、B两个服务，相互依赖时会造成事务失效，简要代码如下： > AServiceImpl ```java @Service(interfaceClass=IAService.class,group="test",version="1.0.0") @Transactional public class AServiceImpl implements IAService { @Autowired private ITestService testService; @Autowired private IBService bService; @Override public void test(String string) { TestEntity testEntity = new TestEntity(); testEntity.setTest("A-"+string); testEntity = testService.save(testEntity); if(!Objects.isNull(testEntity.getId())){ throw new RuntimeException("AService test....a..."); } } } ``` > BServiceImpl ```java @Service(interfaceClass=IBService.class,group="test",version="1.0.0") @Transactional public class BServiceImpl implements IBService { @Autowired private ITestService testService; @Autowired private IAService aService;//相互引用，但实际并未使用 @Override public void test(String string) { TestEntity testEntity = new TestEntity(); testEntity.setTest("B-"+string); testEntity = testService.save(testEntity); if(!Objects.isNull(testEntity.getId())){ throw new RuntimeException("BService test...b...."); } } } ``` > test ```java @RunWith(SpringRunner.class) @SpringBootTest public class SpringbootDubboDemoApplicationTests { @Autowired private ITestService testService; @Reference(group = "test", version = "1.0.0") private IAService iaService; @Reference(group = "test", version = "1.0.0") private IBService ibService; @Test public void testDubbo(){ System.out.println("start......"); try { iaService.test("aaaa"); }catch (Exception e){ e.printStackTrace(); } try { ibService.test("bbbbb"); }catch (Exception e){ e.printStackTrace(); } } } ``` ### Expected Result 正常执行过后，事务应该回滚，数据库中没有保存数据 ### Actual Result 实际结果，a服务执行，数据库中存在记录 A-aaaa 被插入数据库 当注释掉A/B的循环依赖时，结果正常，数据库中没有数据 详细代码见：[https://github.com/softxiang/springboot-dubbo-demo](https://github.com/softxiang/springboot-dubbo-demo) 另有一个问题如下： @Service(interfaceClass=IAService.class,group="test",version="1.0.0") @Transactional public class AServiceImpl implements IAService 此种情况定义了一个dubbo service，是否还需要spring扫描这个service 看代码情况是不需要spring再做相应操作，但看网上很多文章包括issues中依然有人提类似问题 [#2093](https://github.com/apache/incubator-dubbo/issues/2093) 一个服务既是dubbo服务又是本地服务时，是否只需要注册为dubbo的service即可？ @Autowired private IBService bService; 是否会自动区分本地service调用 还是dubbo service?
